    • String like a round shoelace
Size: 28 in Color: Black
I like these due to being soft and easy to pull my sunglasses down and have them right there and put the on and wear and not feeling them on my glasses. Can tighten strap if needed or leave loose if just wearing and want ease of raising and lowering.

The Fathom Cord eliminates this potential tragedy. ... show more
